Pontifications

"As of the November 2016 release, Raspbian has the SSH server disabled by default. It can be enabled manually from the desktop:

Launch Raspberry Pi Configuration from the Preferences menu

Navigate to the Interfaces tab

Select Enabled next to SSH

Click OK

Alternatively, raspi-config can be used:

Enter sudo raspi-config in a terminal window

Select Interfacing Options

Navigate to and select SSH Choose Yes

Select Ok

Choose Finish

Enable SSH on a headless Raspberry Pi

For headless setup, SSH can be enabled by placing a file named ssh, without an extension, onto the boot partition of the SD card. When the Pi boots, it looks
for the ssh file. If it is found, SSH is enabled, and the file is deleted. The
content of the file does not matter: it could contain text, or nothing at all."
